I need to define a NIC for my windows substrate as a variable.

current workflow:

User selects subnet string from predefined variable >

Pre-Create Parses and sets the subnet variable to the json from previous step.

 

The NIC can be connected to

one of n(x) subnets that are defined in the following escript:

subnet1 = {	"name": "name",    "uuid": "redacted_uuid"    }subnet2 = {	"name": "name",    "uuid": "redacted_uuid"    }subnet3 = {	"name": "name",    "uuid": "redacted_uuid"    }subnets = {    "Preprod": subnet1,    "Preprod": subnet2,    "Prod-IaaS": subnet3      }print("{}".format(json.dumps(subnets.get("@@{appSubnet}@@"))))

Output: @@{setSubnet}@@

Profile Configuration: 

 

This is where it breaks:

Hey,

I used a precreate task and just did as below 

 

network_1 = {"name":"VLAN101","uuid":"e37b22d1-45be-49f6-8bf3-0c5dc69d68cf"}
print "network1={}".format(json.dumps(network_1))

 

This works for me. I could not attach the BP here. but the launch works without failure of load json.

Hey, 

Before printing the subnet json, do a json.dumps and print the same.

nic1=<value>

print “nic1=”,json.dumps(nic1)

I have formatted the output as you recommended. I am still seeing this issue.

I guess my question is if I only wanted to set my NIC as a variable that is plain text/json what would that look like?  because I set a variable to the following:

setSubnet:nic1="{"name": "BD-CTXApp-Prod-IaaS", "uuid": "015157ec-9c42-42d4-99ce-d5dcaef86dca"}"

and I set the NIC configuration to the same vairable and I got the same JSON failed to load issue.

Charan, Can you share the BP with me another way I am still unable to get this to work.

Uploaded the BP . can you check and let me know.

Charan,

 

I was not setting the variable correctly. The set variable task creates a new instance of a variable it does not overwrite any existing variables.

 

Once I properly configured the variable it accepted the json value.
